This 'struct timespec' initialization is non needed as we call clock_gettime() right away which is supposed to fill it in. The real reason of removing this init is when compiled by clang with -O0 etc (i.e. compiler flags set when GCOV=1 env var is present), clang inserts a call to memset to initialize the structure. This, of course, leads to "compel piegen" complaining: Unexpected undefined symbol: `memset'. External symbol in PIE? One way of solving it would be to provide a memset() which will call builtin_memset(), or a simple C implemenation. But as this is the only place that triggers such a call to memset(), and this initialization is not really needed, it's easier just to remove it. Now, there might be more cases like this in the future, but for now we are good. Signed-off-by: Kir Kolyshkin <kir@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com> |

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
A video tour on basic CRIU features
